Hey thanks for playing, and great video! The shelf puzzle is a little confusing but on the table in the center of the room is a photo that shows the correct arrangement. We made this project for a game jam, and had a number of problems compiling the project before the submission and a couple features broke or weren't added in time, such as a highlight on intractable objects and a blink mechanic. Since we had such fun making this game and are pumped to see it finished, we will be fixing these problems over the next two weeks. We would love it if you checked back later to play the game after these changes or kept an eye out for development updates.
